Introduction: As ageing progresses, all organs and tissues of the human body are degenerated and functionally lost. As the physical function decreases, the elderly increase instability during physical activity, increasing the risk of falls and fractures. Aims: This study was conducted to investigate the correlation between cognitive function, physical function, and fall risk of the elderly in the nursing hospital. Methodology: The subjects of the study were 38 elderly people in the nursing hospital. Tetrax was used to assess the risk of falls. To measure cognitive function, it was measured using the MMSE-K test. In addition, static balance, dynamic balance, walking ability, and lower extremity muscle strength were evaluated to measure physical function. Static balance was measured using Biorescue, the dynamic balance was time up and go, the walking ability was 10 MWT, and lower extremity muscle strength was measured using five times sit to stand test. Pearson__ampersandsignrsquo;s correlation analysis was used to analyze the correlation between cognitive function and physical function and the risk of falls. Results: As a result of the study, there was a non-significant correlation in the correlation between cognitive function and fall risk (p__ampersandsigngt;.05), and in the correlation between physical function and fall risk, there was a significant correlation in static balance, dynamic balance, gait ability, and lower extremity muscle strength. Showed a relationship (p__ampersandsignlt;.05). Conclusion: As a result of this study, balance training, gait training, and lower extremity muscle strengthening exercises should be performed for the elderly in hospitals and communities.
